Hallador Energy Company

Notes to Condensed Consolidated Financial Statements

(unaudited)

(1)

GENERAL BUSINESS

The condensed consolidated financial statements include the accounts of Hallador Energy Company (hereinafter known as “we, us, or our”) and its wholly owned subsidiaries Hallador Power Company, LLC (“Hallador Power”), Sunrise Coal, LLC (“Sunrise”), and Hourglass Sands, LLC (“Hourglass”), as well as Hallador Power and Sunrise’s wholly owned subsidiaries.

Our business is organized based on the services and products we provide in two segments: (i) Electric Operations and (ii) Coal Operations. The Chief Operating Decision Maker (“CODM”), who is the Company’s Chief Executive Officer, reviews and assesses operating performance measures related to our Electric Operations and our Coal Operations segments.

In addition to these reportable segments, the Company has a “Corporate and Other and Eliminations” category, which is not significant enough, on a stand-alone basis, to be considered an operating segment. Corporate and Other and Eliminations primarily consist of unallocated corporate costs and activities, including a 50 % interest in Sunrise Energy, LLC (“Sunrise Energy”), a private gas exploration company with operations in Indiana and Oaktown Gas, LLC, which we account for using the equity method.

The Electric Operations reportable segment includes electric power generation facilities of the Merom Power Plant (“Merom”).

The Coal Operations reportable segment includes our currently operating underground mining complex Oaktown 1. We have other mining complexes and locations which were idled during the year ended December 31, 2024.

All significant intercompany accounts and transactions have been eliminated. Certain reclassifications have been made to the Company’s prior period condensed consolidated financial information to conform to the current period presentation. These presentation changes did not impact the Company’s condensed consolidated net income (loss), consolidated cash flows, total assets, total liabilities or total stockholders’ equity.

The interim financial data is unaudited; however, in our opinion, it includes all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the results for the interim periods. The condensed consolidated financial statements included herein have been prepared pursuant to the Securities and Exchange Commission’s (the “SEC”) rules and regulations; accordingly, certain information and footnote disclosures normally included in generally accepted accounting principles (“GAAP”) financial statements have been condensed or omitted.

The results of operations and cash flows for the three and six months ended June 30, 2025, are not necessarily indicative of the results to be expected for future quarters or for the year ending December 31, 2025.

Our organization and business, the accounting policies we follow, and other information are contained in the notes to our consolidated financial statements filed as part of our 2024 Annual Report on Form 10-K . This quarterly report should be read in conjunction with such Annual Report on Form 10-K.

RECENT ACCOUNTING PRONOUNCEMENTS

Recent Accounting Pronouncements - Adopted

For the year ended December 31, 2024, the Company retrospectively adopted Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). See “ Note 14 – Segments of Business ” for enhanced disclosures associated with the adoption of ASU 2023-07.

5

Recent Accounting Pronouncements – Not Yet Adopted

In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 primarily requires enhanced disclosures to (1) disclose specific categories in the rate reconciliation, (2) disclose the amount of income taxes paid and expensed disaggregated by federal, state, and foreign taxes, with further disaggregation by individual jurisdictions if certain criteria are met, and (3) disclose income (loss) from continuing operations before income tax (benefit) disaggregated between domestic and foreign. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. We are currently evaluating the impact of adopting ASU 2023-09, but do not expect it to have a material effect on our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversion of Convertible Debt Instruments. The objective of the standard is to improve the relevance and consistency in application of the induced conversion guidance in Subtopic 470-20, Debt with Conversion and Other Options. This standard will affect entities that settle convertible debt instruments for which the conversion privileges are changed to induce conversion. The guidance will be effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company is currently evaluating the impact of the new standard on its financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting-Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The standard update improves the disclosures about a public business entity’s expenses by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation and amortization) included within income statement expense captions. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The standard will be applied on a prospective basis, with retrospective application permitted. The Company is currently evaluating the impact of adoption of the standard on its financial statement disclosures.

LONG-LIVED ASSET IMPAIRMENTS

During the year ended December 31, 2024, the Company recorded a $ 215.1 million non-cash impairment charge in our Coal Operations segment due to the results of our annual business plan review. As part of that business plan review, the Company evaluated core hole samples at several of our mines, noting the samples obtained at our Oaktown 2 mine were determined to be of a lower quality and density than that of the Oaktown 1 mine. As such, the Company decided to temporarily seal the Oaktown 2 mine, and to focus coal production at the Oaktown 1 mine, which has lower recovery costs.

The fair values of the impaired assets were determined using a discounted cash flow model, which represents Level 3 fair value measurements under the fair value hierarchy.  The fair value analysis used assumptions regarding the projected economics of the Coal Operations assets, given prevailing commodity prices and operating expense levels.

For the three and six months ended June 30, 2025, no impairment charges were recorded for long-lived assets.

(4)

INVENTORY

Inventory is valued at a lower of cost or net realizable value (NRV). As of June 30, 2025, and December 31, 2024, coal inventory includes NRV adjustments of $ 0.1 million and $ 0.3 million, respectively.

BANK DEBT

On June 27, 2025, the Company executed the Third Amendment (“Third Amendment”) to the Fourth Amended and Restated Credit Agreement, dated as of August 2, 2023 (as amended, the “Credit Agreement”), with PNC Bank, National Association (in its capacity as administrative agent, "PNC"), which was accounted for as a debt modification. The primary purpose of the Third Amendment was to provide additional operating flexibility for the remainder of 2025 by redefining covenants, deferring certain covenants until the third quarter of 2025 and moving our October 2025 payment to January 2026. The Third Amendment provides for additional flexibility for the Company to enter into prepaid forward power sale contracts, provided that the Company maintains one hundred percent of the outstanding aggregate principal balance of the Credit Agreement (“Term Loan”) as a compensating balance. During the second quarter of 2025, the Company entered into a $ 35.0 million prepaid forward power sales contract, as noted in “Note 7 – Revenue” of which $ 19.0 million of the proceeds were deposited into a money market account with the administrative agent. The compensating balance is classified as “restricted cash” on the condensed consolidated balance sheets at June 30, 2025. As part of the Third Amendment, the required October 2025 principal payment of $ 6.0 million and the January 2026 principal payment of $ 6.5 million, pursuant to the Term Loan, are both now due in January 2026. The balance of the Term Loan will be fully repaid no later than March 2026. All payments will be funded by withdrawals from our compensating balance held in our money market account. Furthermore, the Third Amendment defines certain administrative changes which include, among other things modifications to the required timelines related to reporting and the removal of third-party financial advisors.

Bank debt increased by $ 1.0 million during the six months ended June 30, 2025. Bank debt totaled $ 45.0 million and is comprised of our Term Loan ( $ 19.0 million as of June 30, 2025) and a $ 75.0 million revolver ( $ 26.0 million borrowed as of June 30, 2025) under the Credit Agreement. Our debt is recorded at amortized cost, which approximates fair value due to the variable interest rates in the agreement and is collateralized primarily by our assets.

Liquidity

As of June 30, 2025, we had additional borrowing capacity of $ 32.8 million under the revolver and total liquidity of $ 42.0 million. Our additional borrowing capacity is net of $ 16.2 million in outstanding letters of credit as of June 30, 2025 that were required to maintain surety bonds and other credit support obligations . Liquidity consists of our additional borrowing capacity and cash and cash equivalents.

The Company is currently in discussions with members of its existing bank group and other lenders to refinance our current Credit Agreement. The revolving credit facility matures July 31, 2026 and our Term Loan matures March 31, 2026. The balance of the Term Loan is scheduled to be repaid in January 2026 and March 2026, utilizing restricted cash as set forth in the Third Amendment. As such, the Term Loan is listed as current on the June 30, 2025 condensed consolidated balance sheet. While no definitive agreement has been reached as of the reporting date, management believes it is probable that the Credit Agreement will be refinanced on market terms and conditions for similar situated borrowers and consistent with the existing Credit Agreement. However, there can be no assurance that such efforts will be successful or completed on favorable terms. Failure to refinance our Credit Agreement debt prior to maturity could adversely affect the Company’s liquidity and financial condition.

Fees

Unamortized bank fees and other costs incurred in connection with our initial facility totaled $ 4.3 million. Additional costs incurred with our Debt Agreement amendments totaled $ 0.9 million, of which $ 0.3 million related to our Third Amendment . These unamortized bank fees were deferred and are being amortized over the term of the loan. Unamortized bank fees as of June 30, 2025, and December 31, 2024, were $ 1.9 million and $ 2.5 million, respectively. Unused borrowing capacity under the facility was $ 32.8 million as of June 30, 2025. Commitment fees on the unused portion of the facility are 0.50 % per annum.

Covenants

The Third Amendment, among other things, deferred the Maximum Leverage Ratio and Minimum Debt Service Coverage Ratios until September 2025. The Maximum Leverage Ratio requirement was changed to 3.00 to 1.00 for our fiscal quarter ending September 30, 2025, and is 2.25 to 1.00 thereafter. The Debt Service Coverage Ratio requirement was changed to 3.25 to 1.00 as long as the Company maintains the required compensating balance, if not, remains at 1.25 to 1.00. The Third Amendment removed the First Lien Leverage Ratio while maintaining the minimum liquidity requirement of $ 10.0 million, as defined in the First Amendment to the Credit Agreement.

As of June 30, 2025, we were in compliance with all other covenants defined in the Credit Agreement.

Interest Rate

The interest rate on the facility ranges from secured overnight financing rate (“SOFR”) plus 4.00 % to SOFR plus 5.00 %, depending on our Leverage Ratio. As of June 30, 2025, we were paying SOFR plus 5.00 % on the outstanding bank debt which equates to an all-in rate of 9.43 %.

REVENUE

Revenue from Contracts with Customers

We account for a contract with a customer when the parties have executed the contract and are committed to performing their respective obligations, the rights of each party are identified, payment terms are identified, the contract has commercial substance, and it is probable substantially all the consideration will be collected. We recognize revenue when we satisfy a performance obligation by transferring control of a good or service to a customer.

Electric operations

We concluded that for a Power Purchase Agreement (“PPA”) that is not determined to be a lease or derivative, the definition of a contract and the criteria in ASC 606, Revenue from Contracts with Customers (“ASC 606”), is met at the time a PPA is executed by the parties, as this is the point at which enforceable rights and obligations are established. Accordingly, we concluded that a PPA that is not determined to be a lease or derivative constitutes a valid contract under ASC 606.

We recognize revenue daily, based on an output method of capacity made available as part of any stand-ready obligations for contract capacity performance obligations and daily, based on an output method of MWh of electricity delivered.

For the delivered energy performance obligation in the PPA with Hoosier, we recognize revenue daily for actual delivered electricity plus the amortization of the contract liability as a result of the Asset Purchase Agreement with Hoosier. For delivered energy to all other customers, we recognize revenue daily for the actual delivered electricity.

When energy hours at the Merom Hub are priced below our production cost or during outages at Merom, we have the option to make net hourly purchases of power in the MISO market. We record these as “cost of purchased power” on our condensed consolidated statements of operations.

Coal operations

Our coal revenue is derived from sales to customers of coal produced at our facilities. Our customers typically purchase coal directly from our mine sites where the sale occurs and where title, risk of loss, and control pass to the customer at that point. Our customers arrange for and bear the costs of transporting their coal from our mines to their plants or other specified discharge points. Our customers are typically domestic utility companies. Our coal sales agreements with our customers are fixed-priced, fixed-volume supply contracts, or include a pre-determined escalation in price for each year. Price re-opener and index provisions may allow either party to commence a renegotiation of the contract price at a pre-determined time. Price re-opener provisions may automatically set a new price based on the prevailing market price or, in some instances, require us to negotiate a new price, sometimes within specified ranges of prices. The terms of our coal sales agreements result from competitive bidding and extensive negotiations with customers. Consequently, the terms of these contracts vary by customer.

Coal sales agreements will typically contain coal quality specifications. With coal quality specifications in place, the raw coal sold by us to the customer at the delivery point must be substantially free of magnetic material and other foreign material impurities and crushed to a maximum size as set forth in the respective coal sales agreement. Price adjustments are made and billed in the month the coal sale was recognized based on quality standards that are specified in the coal sales agreement, such as Btu factor, moisture, ash, and sulfur content, and can result in either increases or decreases in the value of the coal shipped.

Disaggregation of Revenue

Revenue is disaggregated by revenue source for our electric operations and by primary geographic markets for our coal operations, as we believe this best depicts how the nature, amount, timing, and uncertainty of our revenue and cash flows are affected by economic factors.

Performance Obligations

Electric Operations

We concluded that each megawatt hour (“MWh”) of delivered energy is capable of being distinct as a customer could benefit from each on its own by using/consuming it as a part of its operations. We also concluded that the stand-ready obligation to be available to provide electricity is capable of being distinct as each unit of capacity provides an economic benefit to the holder and could be sold by the customer.

During the second quarter of 2025, we entered into a 17-month , $ 35.0 million prepaid physically delivered power contract in which Hallador will provide a total of 971,088 MWh to be delivered at various periods starting in July 2025 through November 2026. As the total amount paid up-front by the customer differs from the stand-alone selling price of the transferred power, the Company concluded the contract contains a significant financing component. The contract liability associated with the $ 35.0 million prepayment will be accreted over the agreement term based upon the Company’s incremental borrowing rate which approximates 9.50 %, and the accretion will be separately recognized as interest expense.

Coal Operations

A performance obligation is a promise in a contract with a customer to provide distinct goods or services. Performance obligations are the unit of account for purposes of applying the revenue recognition standard and therefore determine when and how revenue is recognized. In most of our coal contracts, the customer contracts with us to provide coal that meets certain quality criteria. We consider each ton of coal a separate performance obligation and allocate the transaction price based on the base price per the contract, increased or decreased for quality adjustments.

The following table illustrates the balance of all current Electric and Coal Operations contracts allocated to performance obligations that are unsatisfied or partially unsatisfied as of June 30, 2025 and disaggregated by segment and contract duration.

Contract Balances

Under ASC 606, the timing of when a performance obligation is satisfied can affect the presentation of accounts receivable, contract assets, and contract liabilities. The main distinction between accounts receivable and contract assets is whether consideration is conditional on something other than the passage of time. A receivable is an entity’s right to consideration that is unconditional.

Under the typical payment terms of our contracts with customers, the customer pays us the contracted price for electricity or capacity. For coal contracts, the customer pays us a base price for the coal, increased or decreased for any quality adjustments. Amounts billed and due are recorded as trade accounts receivable and included in accounts receivable in our condensed consolidated balance sheets. Payments received prior to fulfilling our performance obligations are included in contract liabilities in our condensed consolidated balance sheets.

INCOME TAXES

For the six months ended June 30, 2025 and 2024, we recorded income taxes using an estimated annual effective tax rate based upon projected annual income (loss), forecasted permanent tax differences, discrete items, and statutory rates in states in which we operate. The effective tax rate for the six months ended June 30, 2025 and 2024, was ~ 0 % due to recording of a full valuation allowance and ~ 23 %, respectively. Historically, our actual effective tax rates have differed from the statutory effective rate primarily due to the benefit received from statutory percentage depletion in excess of tax basis. The deduction for statutory percentage depletion does not necessarily change proportionately to changes in income (loss) before income taxes.

SELF-INSURANCE

The Company is self-insured for certain risks, including physical damage and operational liability, related to our non-leased underground mining equipment allocated among four mining units dispersed over seven miles. The Company records a liability for self-insured risks when a loss is both probable and reasonably estimable. The Company had no accrual for self-insurance liabilities as of June 30, 2025 or December 31, 2024.

The Company also self-insures for workers’ compensation claims under a guaranteed cost program. Under this program, the Company is responsible for the first $ 1.0 million per claim up to an aggregate of $ 4.0 million annually. The Company has restricted cash of $ 23.1 million and $ 3.4 million as of June 30, 2025, and December 31, 2024, respectively, which represents cash held and controlled by third parties and is restricted primarily for future workers’ compensation claim payments and the $ 19.0 million compensating balance on our Term Loan (as discussed in “Note 5 – Bank Debt” above). The Company had $ 5.3 million and $ 4.3 million of workers’ compensation reserve as of June 30, 2025 and December 31, 2024 , respectively, in “accounts payable and accrued liabilities” on the condensed consolidated balance sheets.

(11)

FAIR VALUE MEASUREMENTS

We account for certain assets and liabilities at fair value. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. We consider active markets as those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis. We have no Level 1 instruments.

Level 2: Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. We have no Level 2 instruments.

Level 3: Measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from objective sources (i.e., supported by little or no market activity). ARO liabilities use Level 3 non-recurring fair value measures .

12

Nonrecurring Fair Value Measurements

During the fourth quarter of 2024, the Company completed its review of the coal mining facilities and future mining plans. The impairment analysis was based upon the coal mining operating plans of the Company, market driven pricing and cost trends. As part of that analysis, the Company determined the carrying amount of its coal mining long-lived asset group was not recoverable and recorded a non-cash, long-lived asset impairment charge of $ 215.1 million in 2024.

The discounted cash flow model was calculated using projected economics for the Coal Operations assets, using the Company’s mining plan and reserve estimates to be mined and sold at prevailing commodity prices, operating expenses, and production cost levels, which are classified as Level 3 inputs.

Credit Risk

The Company’s financial instruments exposed to concentrations of credit risk consist primarily of cash and cash equivalents, and restricted cash.

The Company’s cash and cash equivalent and restricted cash balances on deposit with financial institutions total $ 32.4 million and $ 12.2 million as of June 30, 2025 and December 31, 2024, respectively, which exceeded FDIC insured limits. The Company regularly monitors these institutions’ financial condition. The Company utilizes large and reputable banking institutions which it believes mitigates these risks. The Company has not experienced any losses in such accounts.

(12)

EQUITY METHOD INVESTMENTS

We own a 50 % interest in Sunrise Energy, LLC, which owns gas reserves and gathering equipment with plans to develop and operate such reserves. Sunrise Energy, LLC, also plans to develop and explore for oil, natural gas, and coal-bed methane gas reserves on or near our underground coal reserves. The carrying value of the investment included in our condensed consolidated balance sheets as of June 30, 2025, and December 31, 2024, was $ 2.2 million and $ 2.1 million, respectively.

The Company also owns a 50 % interest in Oaktown Gas, LLC. Oaktown Gas, LLC operates an emission abatement project through the destruction of gases extracted from the Oaktown mines to generate carbon credits and other emissions offset credits. The carrying value of the investment included in the condensed consolidated balance sheets as of June 30, 2025, and December 31, 2024, was $ 0.7 million and $ 0.5 million, respectively.

ORGANIZATIONAL RESTRUCTURING

On February 23, 2024, (the “Effective Date”), we committed to a reorganization effort in the Coal Operations Segment (the “Reorganization Plan”) that included a workforce reduction of approximately 110 employees, or approximately 12 % of the workforce. The reduction in workforce was communicated to employees on the Effective Date and implemented immediately, subject to certain administrative procedures. The Reorganization Plan was designed to strengthen our financial and operational efficiency and create significant operational savings and higher margins in our Coal Operations segment. This step helped advance our transition from a company primarily focused on coal production to a more resilient and diversified integrated independent power producer (“IPP”). As part of this initiative, we substantially idled production at our higher cost surface mines, Prosperity Mine and Freelandville Mine, with minimal ongoing production. We also focused our seven units of underground equipment on four units of our lowest cost production at our Oaktown Mine. In connection with the Reorganization Plan, we incurred aggregate expenses of $ 1.9 million ($ 1.1 million in the first quarter of 2024 and $ 0.8 million in the second quarter of 2024) that were included in “labor” in the condensed consolidated statements of operations. These charges related to compensation, tax, professional, and insurance related expenses are considered one-time charges paid during 2024. The coal mining properties asset group was tested for impairment as result of the organizational restructuring passing the undiscounted recoverability test.

SEGMENTS OF BUSINESS

Our business is organized based on the services and products we provide in two segments: (i) Electric Operations and (ii) Coal Operations. The Chief Operating Decision Maker (“CODM”), who is the Company’s Chief Executive Officer, reviews and assesses operating performance measures related to our Electric Operations and our Coal Operations segments.

Our Electric Operations segment includes the electric power generation facilities of our Merom power plant, which is a two unit, 1080 -megawatt rated coal fired power plant located in Sullivan County, Indiana. Our sales region is in MISO Zone 6, which includes Indiana and a portion of western Kentucky. Revenues from our Electric Operations segment consist primarily of delivered energy and capacity revenues. Fuel costs included in our Electric Operations segment include the cost of coal purchased from our Coal Operations segment, which are based on multi-year contracts which approximate market prices at the time the contracts are entered into.

Our Coal Operations segment includes the Oaktown 1 underground mining complex, as well as other currently idled mining facilities, which produce high-quality bituminous coal from the Illinois Basin. Revenues from our Coal Operations segment consist of sales of coal to various third-parties and to Merom. Coal sales to our Electric Operations are based on multi-year contracts which approximate market prices at the time the contracts are entered into. Intercompany coal sales and amounts above actual costs to produce the coal are eliminated in the consolidated statements of operations.

In addition to these reportable segments, the Company has a “Corporate and Other and Eliminations” category, which is not significant enough, on a stand-alone basis, to be considered an operating segment. Corporate and Other and Eliminations primarily consist of unallocated corporate costs and activities, including our equity method investments.

The CODM evaluates segment performance based upon EBITDA margin for each business segment. EBITDA margin is calculated for each segment as follows:

1. For our Electric Operations segment, EBITDA margin is comprised of delivered energy revenues less certain significant segment expenses, which include (i) variable costs, (ii) other operating and maintenance costs, (iii) costs of purchased power, (iv) utilities, (v) labor and (vi) general and administrative costs. (i) Variable operating costs are comprised of fuel costs and certain other operating costs, such as limestone and soda ash.

2. For our Coal Operations segment, EBITDA margin is comprised of coal sales less certain significant segment expenses, which include (i) fuel, (ii) other operating and maintenance costs, (iii) utilities, (iv) labor and (v) general and administrative costs.

EBITDA margin for each segment is a key measure used by our CODM and provides information about our core operating performance, significant expenses and ability to generate cash flow. Additionally, EBITDA margin provides investors with the financial analytical framework upon which our CODM bases financial, operational, compensation and planning decisions and presents a measurement that investors, rating agencies and debt holders have indicated is useful in assessing us and our results of operations. Our CODM reviews variable costs, as defined above, in our Electric Operations segment in order to evaluate the efficiency of that segments operations.

CONTINGENCIES

Our Coal Operations subsidiary is party to litigation in which the plaintiffs allege violations of the Fair Labor Standards Act and state law due to alleged failure to compensate for time "donning" and "doffing" equipment and to account for certain bonuses in the calculation of overtime rates and pay. In January 2025, we agreed to settle with the plaintiffs such litigation for $ 2.8 million, which was recorded in “operating expenses” on our consolidated statements of operations for the year ended December 31, 2024 and is in “accounts payable and accrued liabilities” on our condensed consolidated balance sheets at June 30, 2025.

(17)

SUBSEQUENT EVENTS

On July 1, 2025, the Company amended a third party customer’s coal supply sales agreement increasing contractual tons delivered by 0.3 million and 0.1 million, or $ 13.0 million and $ 2.6 million in revenue, for 2025 and 2026, respectively.

On July 4, 2025, the U.S. H.R.1, an act to provide for reconciliation pursuant to title II of H. Con. Res. 14. (“the OBBBA”) was enacted. The OBBBA introduces multiple tax law and other legislative changes, including modifications to income tax provisions such as domestic research and development expenses, capital expenditures, and U.S. taxation of international earnings; the repeal or acceleration of the sunset of certain tax credits under the 2022 Inflation Reduction Act and elimination of certain penalties for violations of certain regulatory credit programs. The Company is analyzing the potential impacts of this legislation on its business and does not anticipate there to be a material impact as a result.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THE FOLLOWING DISCUSSION UPDATES THE MD&A SECTION OF OUR 2024 ANNUAL REPORT ON FORM 10-K AND SHOULD BE READ IN CONJUNCTION THEREWITH.

We are pleased with our positive results in the second quarter, which is especially encouraging given that energy pricing and demand in the spring season is typically lower due to milder weather. During the quarter we generated $102.9 million of revenue with $17.6 million of EBITDA margin, an improvement of $9.1 million of EBITDA margin over the same period a year ago.

One of our two generating units at Merom was out of service for planned maintenance during the majority of the quarter. We benefited from higher-than-expected energy prices and consistent energy volumes from the generating unit that was in operation. We also saw positive results in our Coal Operations segment, including improvements in our coal production, operating costs and recovery metrics at our Oaktown mining complex. These improvements, in addition to the planned outage at Merom, resulted in higher coal inventory levels companywide. We expect coal inventories to decrease in the second half of 2025 based on increased coal shipments and greater energy generation at Merom now that this year’s planned outage is completed.

The Company continued its strategy of supplementing periods of weaker pricing with limited sales of firm energy. These firm energy sales help to mitigate the impacts of inconsistent weather and fluctuating energy prices and allowed us to focus on maximizing the value of Merom in a way that balances challenging periods while also giving us flexibility to capture upside opportunity in periods of elevated pricing, like we saw in June. In late June, we expanded our relationship with one of our firm energy counterparties, entering into a $35.0 million prepaid forward power sales contract with energy to be delivered at various periods throughout 2025 and 2026. In connection with this agreement, we also entered into the Third Amendment to our Credit Amendment, which moved the required Term Loan payment from October 2025 to January 2026 and adjusted various covenants to provide additional operating flexibility throughout the summer and into the fourth quarter. The prepaid funds will be used in a variety of ways, including fully cash collateralizing the outstanding $19.0 million Term Loan principal balance under the Credit Agreement and to support company operations.

Turning to our negotiations in support of a long-term power purchase agreement with a utility or data center developer, we have seen significant interest in our capacity and energy offerings throughout the quarter. Following the termination of our exclusivity agreement with a leading global data center developer, we have seen a high level of engagement from third parties, including other data center developers and utilities. Each of the interested parties brings a different perspective to the negotiations and each presents opportunities and challenges to effectively monetize our capacity and energy offerings. While we remain in contact with our original counterparty, we are encouraged by our discussions with several of these newly interested parties. We believe that the evolving energy markets, specifically as related to data center growth and favorable utility demand, as well as the favorable regulatory environment, provide the potential to leverage opportunities that simply were not available when we began the request for a proposal process last summer. The utility discussions that we are currently engaged in are intrinsically more straightforward to negotiate, can be implemented sooner and could result in greater sales volumes of energy and accredited capacity. We anticipate pricing will be around the energy curve with terms of ten years or more. As we have highlighted in previous disclosures, many of the non-utility arrangements are inherently complex and involve multiple parties, which adds time and alignment challenges to the negotiation process. Notwithstanding those challenges, returning to non-exclusive negotiations has reinforced our belief that in the end, we will forge a strategic partnership that will create significant value for years to come.

Over the last several quarters, we have highlighted our belief that the prevailing industry trend of retiring dispatchable generators, including coal, in favor of non-dispatchable resources such as wind and solar will create an unbalanced energy equation, reduce reliability and increase long-term volatility in the energy markets. It is our position that the enhanced reliability of dispatchable generation, like Merom, versus non-dispatchable generators will increase the value of the attributes of Hallador Power in the overall energy markets. In light of this, we continue to evaluate how to further enhance this value. As we have previously discussed, we are actively seeking acquisition opportunities for additional dispatchable generation, which we believe will help diversify our risk and provide opportunities to upsize strategic future

21

arrangements. We believe that this approach has the potential to enhance our financial flexibility and strengthen our position in the evolving energy market.

Additionally, we see the potential of enhancing the reliability, resiliency and flexibility of Merom by adding natural gas and creating a dual fuel scenario, if and when the opportunity makes operational and financial sense. While we are still in the evaluation process, by adding the capability to co-fire with gas or coal, we believe that it could provide Hallador Power the ability to take advantage of the best fuel cost scenario and better control our operating expenses. We believe that the ability to co-fire with natural gas and/or coal will also provide increased resiliency in times where gas availability is traditionally limited, as we have seen in various winter storms across the last several years. This co-firing also allows us to retain the advantage of operating our Sunrise Coal subsidiary and leveraging our own coal supply to prevent unreasonable price increases by third party providers while simultaneously supporting our workforce and the surrounding community. This evaluation is complex on a variety of levels, specifically customer preference and an evolving regulatory environment that could have material impacts on the timing and economic benefits of undertaking such a change.

We continue to invest in the future of the plant through extensive maintenance and capital expenditures. We had one unit out of service for planned maintenance for most of the quarter and extending into early third quarter. We typically choose the shoulder season periods for these planned maintenance outages as power demand and pricing in spring are traditionally lower than in other parts of the year. We also try to limit our firm energy sales during these periods to guard against any unforeseen or forced outages, which have the potential to expose us to spot market pricing. Despite the outage, we saw stronger than expected prices in June, which we were able to take advantage of with the unit that remained online. As illustrated in the solid forward sales position table below, in 2026, we currently have 4.0 million delivered energy MWh contracted at an average sales price of $43.05 per MWh. We continue to see higher demand and increase in our average contracted sales price. Our largest PPA contract will see an increase of more than $20.00 per MWh in 2026 as compared to 2025 on expected volumes of approximately 1.6 million MWh. Following 2026, we are optimistic that we will be able to sell energy at higher prices in support of data center development and/or to traditional wholesale customers in line with the indicators of a strong forward curve.

We believe that Hallador is uniquely positioned to transform retiring and/or underperforming assets into future opportunities. This will enable us to supply high demand end users, such as data centers and on-shored industrial customers, with minimal impact to retail consumers, unlike a traditional utility siphoning off consumer power to serve these types of large load end-users. By continuing the operations of the dispatchable plants to support large load industrial users as the utilities transition to non-dispatchable generation, the new generation becomes additive to the already struggling grid rather than cannibalizing the overall reliability of what exists today. We remain optimistic about the potential to add to our strategic portfolio and the long-term benefits that such a transaction could produce for the company, its shareholders and its customers. This model for growth enables us to capture value from the critical factors limiting artificial intelligence and data center growth, accredited capacity and reliable and affordable energy. Importantly, the positive momentum that we continue to see from the current administration on both the federal and state levels should make transactions of this sort more feasible than they would have been under the prior administration.

Shifting to our Coal Operations, we continue to see the benefits of our 2024 organizational restructuring. While much of the last year was focused on optimizing production, headcount, and strategy to best support our Electric Operations and our existing third-party coal contracts, we have seen improved operational expenses, more efficient recoveries and accelerating shipments. As we have said before, this organizational restructuring should provide us with greater flexibility to quickly scale if we see coal prices increase to a point that justifies restarting production at higher cost units. Additionally, while our coal inventories are elevated, we believe that we are well-positioned to meet industry needs in the event that coal plants, including Merom, continue to dispatch at higher levels.

With renewed support of coal mining and coal fired power generation on both the federal and state level, we believe that we are well positioned to take advantage of opportunities for growth and/or expansion. Current market dynamics remain stronger than they have been in the past year, and we continue to evaluate if and when it makes sense to bring on additional coal production in the back half of 2025 and/or 2026. Starting in 2026 our average contracted sales price across all contracts is approximately $4.00 per ton higher than the average contracted sales price in 2025.

22

Notwithstanding this potential to increase production, we currently expect to produce approximately 3.7 million tons of coal in 2025. In the first half of 2025, we produced approximately 2.1 million tons of coal at our Oaktown Mining Complex. We use supplemental coal from third party suppliers at Merom, typically purchased at favorable prices to help diversify self-production supply risk and to provide us additional flexibility in our sales portfolio if prices increase on the spot market. This optionality to obtain low-cost tons either internally or from third-parties while capturing upward swings in the commodity markets for coal should allow us to further maximize margins while optimizing fuels costs at Merom.

The continued transformation of Hallador from a commodity focused producer of coal to an IPP remains our primary focus, while leveraging this transition to capture the expanding margins of the energy markets and capitalize on the soaring demand for reliable electricity. The strong and varied interest that we have experienced following the end of our exclusivity period has been encouraging and we are steadfast in our belief of the value that our strategic transition in support of the economy’s desire for reliable energy will bring. We continue to believe that our business is well positioned to take advantage of opportunities for growth and cash flow generation as they arise.

Our goal is for Hallador Power to generate on average 1.5 million MWh on a quarterly basis, which equates to 6.0 million MWh annually (see Hallador Power’s capacity and utilization information below). During the first six months of the year, Hallador Power generated 2.2 million MWh, or 73.3% of our quarterly target and purchased 0.2 million MWh.

(i).

Nameplate capacity for the Merom Power Plant refers to the maximum electric output generated by the plant in the period presented and may not reflect actual production. Actual production each period varies based on weather conditions, operational conditions, and other factors.

(ii).

Accredited capacity is based on MISO’s average seasonal accreditations for the year. Average seasonal accreditations were 775 MW and 829 MW per day for 2025 and 2024, respectively. Accreditations are weighted and adjusted annually based on 3-year rolling performance metrics.

(iii).

Accredited capacity utilization is measured as power produced (MWh) divided by accredited capacity for the period (MW) multiplied by 24, times the number of days for the period.

When forward selling Capacity, we target annual sales of around $65.0 million to offset our fixed annual costs at the plant of approximately $60.0 million. For 2025, we have contracted approximately $56.0 million or 86.2% of our target. We believe our forward Capacity sales goals are attainable as illustrated in our “Solid Forward Sales Position” table below.

Our condensed consolidated financial statements should be read in conjunction with this discussion. This analysis includes a discussion of metrics on a per mega-watt hour (MWh) and a per ton basis as derived from the condensed consolidated financial statements, which are considered non-GAAP measurements. These metrics are significant factors in assessing our operating results and profitability.

OVERVIEW

The following is an overview our Electric Operations and Coal Operations for Q2 2025 compared to Q1 2025.

I.

Q2 2025 Net Income of $8.2 million.

a. Electric Operations: During the second quarter of 2025, we sold 0.8 million MWh representing a 50.0% decrease in total MWh sold from Q1 2025. This decrease was expected as Q2 typically has lower demand for power and we had a planned maintenance outage on one of our units at Merom for approximately two months during the quarter. Operating revenues increased $17.53 per MWh from the first quarter of 2025. This change was primarily due to the allocation of capacity revenue over lower energy volumes.
i. In Q2 2025, Electric Sales were $60.0 million, or $72.44 per MWh sold, on a segment basis.
ii. In Q2 2025, Electric Operations fuel, other operating and maintenance and cost of purchased power were $34.2 million, or $41.31 per MWh compared to $49.4 million, or $31.59 per MWh in Q1 2025. This increase in costs per MWh was due to lower energy volumes driven by the planned maintenance outage at Merom.
iii. Q2 2025 Electric Operations income before income taxes was $13.99 per MWh, an increase of $1.72 from Q1 2025.
b. Coal Operations: During the second quarter of 2025, 0.9 million tons of coal were shipped on a segment basis, with approximately 0.1 million tons of that being shipped to Merom for $7.4 million. This is a decrease of 0.2 million tons of coal shipped from Q1 2025, on a segment basis. This decrease in coal shipments is mainly driven by a 70.0% reduction in shipments to Merom due to the shoulder season and lower demand for power.
i. In Q2 2025, Coal Operations operating revenues were $45.5 million, or $51.16 per ton, on a segment basis, an increase of $0.02 per ton from Q1 2025.
ii. In Q2 2025, Hallador’s Coal Operations other operating and maintenance costs were $18.2 million, or $20.50 per ton, compared to $23.9 million, or $22.27 per ton, on a segment basis, in Q1 2025.
iii. We recorded income before income taxes for the quarter of $1.58 per ton on a segment basis. This is an increase of $7.56 per ton from Q1 2025.

Q2 2025 vs. Q2 2024

Delivered Energy revenue on a dollar and per MWh basis remained flat quarter over quarter, however MWh generated decreased 0.1 million or 3.3% and MWh purchased increased 0.1 million MWh or 25.4% during the same periods. When energy hours at the Merom Hub are priced below our production cost or during outages at Merom, we have the option to make net hourly purchases of power in the MISO market, which we record as cost of purchased power. Cost of purchased power in Q2 2025 was $2.2 million at an average purchase price of $29.35 MWh compared to $2.6 million at an average price of $44.39 per MWh in Q2 2024.

Fuel costs decreased $3.1 million, or 12.6%, compared to the second quarter of 2024. On a per MWh basis, fuel costs decreased $3.34, or 11.5%. This change was due to decreased production of energy as noted above resulting in 0.1 million tons or 11.4% less tons of coal used. The average purchase price per ton of coal used in the plant on a segment basis, was $53.38 in the second quarter of 2025, decreasing from $54.17 per ton in the second quarter of 2024.

Other operating revenue increased $3.0 million, or 1701.1%, compared to Q2 2024. Other operating revenue on a per MWh basis increased $3.58, or 1704.8%. This change was due to revenue received related to contractual negotiations on the exclusivity agreement.

Electric interest expense increased $1.7 million, or 916.7%, compared to the second quarter of 2024. On a per MWh basis, interest expense increased $2.06, or 936.4%. The increase in our interest expense relates to accretion on our prepaid delivered energy contracts that were entered into in October 2024 and June 2025.

Income before income taxes increased $5.0 million, or 75.3%, compared to the second quarter of 2024. The main drivers of this change in income before income taxes are described in the discussion above.

YTD 2025 vs. YTD 2024

Delivered energy increased $24.0 million, or 26.1%, compared to the first six months of 2024. This increase is attributable to new PPA contracts starting in Q1 2025 that were not in effect during 2024. Total PPA hours delivered in the first six months of 2025 were 1.8 million at an average price of $36.63 per MWh compared to delivery of 1.0 million MWh at an average price of $34.42 for the same period in 2024.

Fuel increased $10.0 million, or 20.4%, compared to the first six months of 2024. The increase in fuel costs were directly related to the increase in MWh generated, requiring the increased use of fuel by 0.2 million tons of coal or 21%. On a per MWh basis, fuel decreased $3.70, or 13.0% at an average cost of $53.65 per ton for 2025 compared to an average cost of $55.80 per ton for 2024.

The cost of purchased power increased $4.5 million, or 98.3%, compared to year-to-date 2024. On a per MWh basis, cost of purchased power increased $1.14, or 43.3%. When energy hours at the Merom Hub are priced below our production cost or during outages at Merom, we have the option to make net hourly purchases of power in the MISO market, which we record as cost of purchased power.

Electric interest expense increased $3.3 million, or 984.7%, compared to the first six months of 2024. On a per MWh basis, interest expense increased $1.32, or 694.7%. The increase in our interest expense relates to accretion on our prepaid delivered energy contracts that were entered into in October 2024 and June 2025.

Income before income taxes increased $9.1 million, or 41.9%, compared to the first six months of 2024. The main drivers of this change in income before income taxes are described in the discussion above.

Q2 2025 vs. Q2 2024

Other operating and maintenance costs decreased $3.4 million, or 15.5%, compared to the second quarter of 2024. On a per ton basis other operating and maintenance costs decreased $4.94, or 19.4%. This change was the result of impacts related to the non-cash impairment charge recognized in Q4 2024 in the amount $215.1 million as well as increased coal production of 0.2 million tons or 19.1% in Q2 2025 over Q2 2024 whereas coal sales increased 0.1 million tons or 4.8% increasing coal inventory.

General and administrative costs decreased $1.6 million, or 45.2%, compared to the second quarter of 2024. On a per ton basis general and administrative costs decreased $1.96, or 47.7%. This change was related to the non-cash impairment charge recognized in Q4 2024 in the amount $215.1 million as well as the retirement of an executive officer in 2024.

29

Depreciation, depletion and amortization decreased $8.6 million, or 96.0%, compared to the second quarter of 2024. On a per ton basis, depreciation, depletion and amortization decreased $10.11, or 96.2%. This change was the result of the non-cash impairment charge recognized in Q4 2024 in the amount $215.1 million as well as a $4.8 million out-of-period adjustment recorded during the second quarter of 2025 due to an overestimate of depreciation, depletion and amortization expense in the first quarter 2025.

Interest expense decreased $1.3 million, or 39.5%, compared to the second quarter of 2024. On a per ton basis, interest expense decreased $1.59, or 42.3%. Our decreased interest expense relates to reductions of convertible debt of $11.0 million and related party debt of $5.0 million.

Income before income taxes increased $15.9 million, or 109.7%, compared to the second quarter of 2024. The main drivers of this change in loss before income taxes are described in the discussion above.

YTD 2025 vs. YTD 2024

Coal sales decreased $11.4 million, or 10.2%, compared to the first six months of 2024. On a per ton basis, coal sales decrease $3.02, or 5.6%. Consolidated coal sales decreased $14.1 million, or 17.1% from 2024. These declines were due to reductions in volume and average sales price for our coal. Our average sales price, on a segment basis, decreased $2.99 per ton and we sold 0.1 million tons less compared to 2024. Our average sales price, on a consolidated basis for 2025 decreased $4.27 per ton and we sold 0.2 million tons less compared to 2024.

Other operating and maintenance costs decreased $11.3 million, or 21.1%, compared to the first six months of 2024. On a per ton basis, other operating and maintenance costs decreased $4.41, or 17.0%. This change was partially the result of the organizational restructuring that occurred in February 2024 extending into Q2 2024 which led to an expected reduction in production costs related to the higher cost mining locations such as roof support and maintenance. Tons sold decreased 0.1 million tons or 4.9% which further decreased royalty expenses.

Labor decreased $8.8 million, or 18.8%, compared to the first six months of 2024. On a per ton basis, labor decreased $3.32, or 14.6%. This change was the result of the organizational restructuring that occurred in February 2024 which reduced the Coal Operations headcount to 655 as of June 30, 2025 from 924 prior to the restructuring.

General and administrative costs decreased $1.7 million, or 28.7%, compared to the first six months of 2024. On a per ton basis, general and administrative decreased $0.72, or 25.0%. This change was related to the non-cash impairment charge recognized in Q4 2024 in the amount $215.1 million as well as the retirement of an executive officer in 2024.

Other operating revenue increased $1.4 million, or 108.3%, compared to the first six months of 2024. On a per ton basis, other operating revenue increased $0.76, or 119.2%. This change was the result of increased utilization of our rail facility by a customer resulting in an increase in transloading fee revenue.

Depreciation, depletion and amortization costs decreased $9.5 million, or 48.3%, compared to the first six months of 2024. On a per ton basis, depreciation, depletion and amortization decreased $4.35, or 45.6%. This change was the result of the non-cash impairment charge recognized in Q4 2024 in the amount $215.1 million.

Interest expense decreased $2.5 million, or 38.7%, compared to the first six months of 2024. Interest expense on a per ton basis decreased $1.10, or 35.6%. Our decreased interest expense primarily relates to reductions of convertible debt of $11.0 million and related party debt of $5.0 million.

Loss before income taxes decreased $25.5 million, or 87.4%, compared to the first six months of 2024. The main drivers of this change in loss before income taxes are described in the discussion above.

INCOME TAXES

Our effective tax rate (ETR) is estimated at ~0% and ~23% for the six months ended June 30, 2025 and 2024, respectively. For the six months ended June 30, 2025, we estimated our annual ETR based upon projected annual income (loss), forecasted permanent tax differences, discrete items, and statutory rates in states in which we operate. Our ETR differs from the statutory rate due primarily to statutory depletion in excess of tax basis and changes in the valuation allowance. The deduction for statutory percentage depletion does not necessarily change proportionately to changes in income (loss) before income taxes.

CRITICAL ACCOUNTING ESTIMATES

We believe that the estimates of coal reserves, asset retirement obligation liabilities, deferred tax accounts, valuation of inventory, and the estimates used in impairment analysis are our critical accounting estimates.

The reserve estimates are used in the depreciation, depletion, and amortization calculations and our internal cash flow projections. If these estimates turn out to be materially under or over-stated, our depreciation, depletion and amortization expense and impairment test may be affected. The process of estimating reserves is complex, requiring significant judgment in the evaluation of all available geological, geophysical, engineering and economic data. The reserve estimates are prepared by professional engineers, both internal and external, and are subject to change over time as more data becomes available. Changes in the reserves estimates from the prior year were nominal.

SMCRA and similar state statutes require, among other things, that surface disturbance be restored in accordance with specified standards and approved reclamation plans. SMCRA requires us to restore affected surface areas to approximate the original contours as contemporaneously as practicable with the completion of surface mining operations. Federal law and some states impose on mine operators the responsibility for replacing certain water supplies damaged by mining operations and repairing or compensating for damage to certain structures occurring on the surface as a result of mine subsidence, a consequence of longwall mining and possibly other mining operations.

Obligations are reflected at the present value of their future cash flows. We reflect accretion of the obligations for the period from the date they are incurred through the date they are extinguished. The ARO assets are amortized using the units-of-production method over estimated recoverable (proven and probable) reserves. We use credit-adjusted risk-free discount rates ranging from 7% to 10% to discount the obligation, inflation rates anticipated during the time to reclamation, and cost estimates prepared by its engineers inclusive of market risk premiums. Activities include reclamation of pit and support acreage at surface mines, sealing portals at underground mines, and reclamation of refuse areas and slurry ponds.

Accretion expense is recognized on the obligation through the expected settlement date. On at least an annual basis, we review our entire reclamation liability and make necessary adjustments for permit changes as granted by state authorities, changes in the timing and extent of reclamation activities, and revisions to cost estimates and productivity assumptions, to reflect current experience. Any difference between the recorded amount of the liability and the actual cost of reclamation will be recognized as a gain or loss when the obligation is settled.

We have analyzed our filing positions in all of the federal and state jurisdictions where we are required to file income tax returns, as well as all open tax years in these jurisdictions. We identified our federal tax return and our Indiana state tax return as “major” tax jurisdictions. We believe that our income tax filing positions and deductions would be sustained on audit and do not anticipate any adjustments that will result in a material change to our consolidated financial position. We have not taken any significant uncertain tax positions, and our tax provisions and returns are prepared by a large public accounting firm with significant experience in energy related industries. Changes to the estimates from reported amounts in the prior year were not significant.

Inventory is valued at a lower of cost or net realizable value (NRV). Anticipated utilization of low sulfur, higher-cost coal from our Freelandville, and Prosperity mines has the potential to create NRV adjustments as our estimated needs change. The NRV adjustments are subject to change as our costs may fluctuate due to higher or lower production and our NRV may fluctuate based on sales contracts we enter into from time to time. As of June 30, 2025, and December 31, 2024, coal inventory includes NRV adjustments of $0.1 million and $0.3 million, respectively.

Long-lived assets used in operations are depreciated and assessed for impairment annually or whenever changes in facts and circumstances indicate a possible significant deterioration in future cash flows is expected to be generated by an asset group. For impairment assessments, management groups individual assets based on a judgmental assessment of the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. The determination of the lowest level of cash flows is largely based on nature of production, common infrastructure, common sales points, common regulation and management oversight to make such determinations. These determinations could impact the determination and measurement of a potential asset impairment. Management evaluates

32

assets for impairment through an established process in which changes to significant assumptions such as prices, volumes and future development plans are reviewed. If, upon review, the sum of the undiscounted pre-tax cash flows is less than the carrying value of the asset group, the carrying value is written down to estimated fair value. Because there usually is a lack of quoted market prices for long-lived assets, the fair value of impaired assets is typically determined based on the present values of expected future cash flows using discount rates believed to be consistent with those used by principal market participants. The expected future cash flows used for impairment reviews and related fair value calculations are typically based on judgmental assessments of future volumes, commodity prices, operating costs and capital investment plans, considering all available information at the date of review. Changes to any of the market-based assumptions can significantly affect estimates of undiscounted and discounted pre-tax cash flows and impact the recognition and amount of impairments.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

No material changes from the disclosure in our 2024 Annual Report on Form 10-K .

ITEM 4. CONTROLS AND PROCEDURES

DISCLOSURE CONTROLS

We maintain a system of disclosure controls and procedures that are designed for the purpose of ensuring that information required to be disclosed in our SEC reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our CEO and CFO and as appropriate to allow timely decisions regarding required disclosure.
